Feeling discomfort and heaviness in the breasts while lying down 10 months post-op after breast implant surgery can have various potential causes. While I'm not a doctor, I can provide you with some general information that might help you understand the situation better: 1.) Healing Process: It's possible that your body is still in the process of healing and adjusting to the presence of the implants. Discomfort can be a normal part of the healing process, especially during the first year after surgery. 2.) Scar Tissue Formation: The development of scar tissue around the implants, known as capsular contracture, can cause discomfort and tightness in the breasts. While this often occurs within the first few months after surgery, it can continue to develop over time. 3.) Implant Size and Position: The size and position of the implants can influence how they interact with your natural breast tissue and chest muscles. If the implants are particularly large or positioned in a way that puts pressure on surrounding tissues, it might lead to discomfort, especially in certain positions. 4.) Nerve Sensitivity: Changes in nerve sensitivity are common after breast augmentation surgery. Nerves can take time to adjust and heal, and this can result in sensations like discomfort, numbness, or tingling. 5.) Underlying Conditions: Other factors like muscle strain, posture issues, or pre-existing conditions could contribute to the discomfort you're experiencing. It's important to communicate your symptoms to your plastic surgeon. They can examine your breasts, review your surgical history, and possibly perform tests or imaging to determine the cause of the discomfort. They will be able to provide you with appropriate guidance and recommendations based on your specific situation. If you experience sudden or severe pain, changes in breast appearance, or any other concerning symptoms, don't hesitate to reach out to your surgeon promptly.
